SPEGIFIGATIQN forming part of Letters Patent No. 305,377, dated September 16, 18,84. Application filed June 20, 1884. (No model.)

To a/ZZ whom, it may concern:

Be it known that we, JOHN DUNLAP and EwALr RIEDEL, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Campaig11-Torches; and we do hereby declare the following to be a full7 clear, and exact description thereof.

Our invention relates to an improvement iu torches; and it consists in the arrangement and construction of devices for securing the frame of the lamp to the stock, as hereinafter more fully appears. n

IVe will now describe our invention so that others skilled in the art to which it appertains may employ the same, reference being` had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a perspective view of our improved torch. Fig. 2 is a plan view of the swivel; and Fig. 3 is a vertical sectional view on the line x x, Fig. 2.

Like letters of reference indicate like parts wherever they occur.

In the drawings, c represents the ferrule or socket, which is designed to fit over the end of the torch pole or stock a and to be seeurely attached thereto. For this purpose it is preferably made in the form of a hollow metallic cap having one end. closed by the outwardly-convex piece I). The other and open end of the socket fits over the end of the torch-pole, and may be secured thereto by a rvet, c. Secured to the socket a by a bolt, c, having a head, cl, is a convex swivel-piece, e, composed of the cup e and flat disk c2, iitting over the mouth of the cup, the bolt d passing loosely through the center of the disk e2 and cup c to the top of the socket a. The bolt is connected with the socket by being made integral therewith, as shown in the drawings, or by inserting the end through the top of the socket and upsetting or otherwise fastening it therein'.

If desired, the disk c2 may t over the cup cJ without being secured thereto, excepting by the head of the bolt d. By these devices a swivel is formed which revolves easily on its axis-the bolt d.

Bolted or otherwise secured to the disk e, 5o ata point near the periphery of the disk and away from its center, is the bracket or frame f', through the ends of the arms of which pass the pintles g g, which are secured to the body i of the lamp, and are ilattened at their outer ends to prevent them from escaping from the frame, so that the lamp is pivotally supported within the two arms f f, the pintles g g forming the axis upon which the lamp may bevertically rotated. Thus constructed, in what- 6o ever positionthe staff of the torch may beheld, the frame f will automatically adjust itself so that the burner 7e will be upright. Thus, if the staff be inclined, as shown in Fig. l, the weight of the body of the torch, acting upon the outer rim of the disk will cause the cup eto turn on its axis-theboltcZ-until the axis g g of the vessel reaches a position at right angles to the plane of the inclination 4of the staff, thus allowing the body of the lamp to 7o swing on its axis into an upright position.

Vvve are aware that this effect has been produced more or less perfectly by other devices than that which we have described, and we do not desire to claim, broadly, pivoting the torch eccentrically upon its staff. The ad` vantages of our improved torch are, however, that the top of the ferrule c, being convex and bearing upon the convex surface of the bottom ofthe swivel, materially aids in the easy 8o adjustment of the lamp,and prevents friction between the parts.

If desired, the cap b of the socket c may be made plane instead of convex, as shown in the drawings; but I prefer the dome shape, as it affords a more perfect bearing-surface for the convex swivel-piece e.

The bolt d, also passing through the disk c2 and `bottom of the cup e', affords a secure attachment without increase of friction. i glo If desired, the arms f f may be inclined, so that the pivots g g are situate in the same vertical plane with the staff c. Owing to the disk e, the torch may be held in an inverted position,when the heat from the burner,striking against the disk e2, is deflected therefrom and prevented from injuring the end of the staff.

Having thus-described our invention, what piece being secured to said socket by means of a. c We claim, and desire to secure by Letters Patp bolt, d, Whichpasses loosely through the base ent, is and top plate of the swivelpieee,and is iixed l.
